Loom attachments for making fringes

ABSTRACT

There is disclosed an apparatus for holding the filling yarn of a shuttleless loom in a position that will prevent the filling carrier from inserting filling in the warp shed while the warp is advanced a sufficient distance to form a fringe.

TOLLISON ATTORNEYS 1 LOOM ATTACHMENTS FOR MAKING FRINGES BACKGROUND OF THE INVENTION On conventional looms such as the Draper DSL loom, the end of the filling'yarn is held by a holding and cutting device while the filling depressor pulls the yarn down to a position such that the filling carrier can pick it up and carry it into the warp.

To form a fringe in the manufacture of cloth material such as towelling for example, the filling yarn or weft is omitted while for a discrete period of time the warp is advanced. This provides a section in the cloth that has warp threads only and when these are out they become a fringed edge. The fringe device presently in use, (for example as shown in US. Pat. No. 3,396,755) moves the filling depressor so that, the filling will not be in position for the carrier to pick up the filling while the fringe is being formed. One disadvantage of this arrangement is that during the time the fringe is being formed, the filling is not positively held and therefore is not always in a position to be picked up by the filling depressor when the fringe is completed. Furthermore, the mechanism for moving the filling depressor requires a cable actuator to hold the depressor away from the filling while the depressor continues to move. This causes a severe strain upon the cable actuation mechanism, with attendant eventual cable failure and expensive shut-down of the loom.

It is the purpose of the present invention to avoid these prior problems and difficulties, by the use of a simplified apparatus.

SUMMARY OF THE INVENTION PREFERRED DESCRIPTION OF THE DRAWING FIG. 1 is a fragmentary prespective view of a fringe attachment constructed according to the present invention; and

FIG. 2 is a side view of the attachment of FIG. 1.

DESCRIPTION OF A PREFERRED EMBODIMENT Referring now to the drawing, a fringe attachment constructed according to the principles of the present invention has been illustrated. The attachment 10 includes a frame or mounting post 11 which is secured in a suitable manner to a loom of the shuttleless type adjacent to the filling yarn depressor 12. The latter is suitably actuated to bring the filling yarn 13 into the path of the carrier 14 which inserts the filling yarn into warp shed.

The fringe attachment provides mounting bracket 16 secured by a bolt 17 in the post 11. The bracket 16 is adjustable laterally with respect to the post by means of an elongated slot 17 in the bracket 16. The bracket 16 has horizontal and vertical legs 16a and 16b. A fringe arm 21 is secured to the leg 16b by means of pivot screw 19 and mounting block 20. The arm 21 can be swung from the vertical position of FIGS. 1 and 2 into the dotted line position by a cable 23 connected to the top end 21a of the arm. The cable .23 will be actuated in a ateral direction by any suitable means which is programmed to effect the making of a fringe periodically in the cloth weaving cycle.

As shown in the drawing, when the arm 21 is swung into the dotted line position, the lower end thereof will hold the filling 13 away from the depressor 1'2 and the carrier 14. In order to provide positive engagement of the arm 21 and the filling thread, the lower end of the arm 21 has been provided with a series of serrations 21b. The pivot screw 19 mounts a spring 21 which exerts a spring force behind the upper end 21a of the arm 21 to return the arm 21 to its vertical position when it is released from the pulling force of cable 23.

The present invention increases loom efficiency since the filling is seldom lost, whereas prior fringe devices did not positively engage the filling and were thus not able positively to recommence the insertion of the filling. This improves the quality of the weave. The fringe attachment further eliminates considerable down time of looms which occurred due to the breaking of the actuating cable holding the moving depressor of the prior fringe device.

It will be understood that the above description is of a particular embodiment of the invention and is therefore merely representative. In order to appreciate fully the scope of the invention reference should be made to the appended claims.

WHAT IS CLAIMED IS:

1. In combination with a loom having a filling depressor for depressing filling yarn and a carrier for receiving said yarn for insertion thereof into a warp shed, the improvement comprising a vertically disposed lever pivotably mounted to swing one end into and out of the path of said filling yarn, a cable attached to one end of said lever for causing said lever to contact said filling yarn to move said yarn away from said depressor for a predetermined period in the weaving cycle in order to form a fringe, providing at least one yarn control groove on said one end of said lever, and a spring connected to said lever for moving said] lever out of contact with said filling yarn upon release of tension from said cable.
